Although it will probably be years before 5G hits Australian cell towers, the future is looking bright. Optus and Huawei have recently completed a 5G network trial, achieving the fastest speeds observed of a single user transmission over 5G in Australia so far.
The trial took place in Sydney and reached a single user transmission rate of 35Gbps over the 73 GHz band. The objective of the trial was to explore spectrum efficiency at millimetre (mm) wave frequencies (above 30GHz), which are key to realising the promise of 5G networks.
Optus is working to lay the building blocks for Next Generation 5G networks – which will provide the capability to download a 1080p movie in seconds – and enable things such as massive Internet of Things, extreme broadband and ultra-low latency applications.
Last month, Optus implemented Cloud Baseband technology with Huawei which pushed peak speeds through inter-site carrier aggregation at the AFL Grand Final. Next year, Optus will deploy Coordinated Heterogeneous Network and trial Massive MIMO (multiple-input and multiple-output). These technologies are a pre-cursor to 5G’s Joint Reception and Massive MIMO concept.
